Guide to Splitting Large Files into Multiple Smaller Files on Windows

Managing large files can often be a hassle, especially when faced with restrictions from email services or messaging platforms. Learning how to efficiently split large files into smaller segments can drastically improve your ability to share and store data. With the help of popular file compression tools like WinRAR and 7-Zip, you can easily divide and later recombine your files. Let’s explore how these tools can be utilized effectively.

Using WinRAR to Split Large Files

WinRAR is renowned for its powerful file compression capabilities, allowing users to split files into multiple volumes that are manageable and easier to share. Start by downloading and installing WinRAR.

Once WinRAR is installed, locate the file you wish to split via File Explorer. Right-click on the file, then select WinRAR > Add to Archive.

In the dialog that appears, the Archive format defaults to RAR, but you can also choose ZIP or RAR4 as needed. Keep the compression method set to Normal and leave the Dictionary size at its default settings, since you’re focusing on file splitting.

Next, input your desired volume size under the Split to Volume, size field. For instance, if you have a 6.34GB file and want to create 1GB parts, simply enter 1GB. If added security is required, you have the option to include a password for the archive.

Once you’ve entered all the details, click OK to commence the splitting process. WinRAR will create the segments in the same directory as the original file, naming them as part1, part2, part3, etc. Patience is key here, as the time taken will depend on the original file size.

To recombine the split files, ensure all segments are located in the same folder. Right-click on the first part and select WinRAR > Extract files. Choose your destination folder and click OK. It’s essential that the recipient has WinRAR installed, as other programs may not recognize the format.

Using 7-Zip to Split Large Files

7-Zip is a versatile and open-source file compression tool that can also split large files effectively. Known for its excellent compression rates, it can be a great alternative to WinRAR. Begin by downloading and installing 7-Zip.

Once installed, open 7-Zip File Manager. Either double-click on Computer, locate your file, and then click Add (represented by a green plus icon), or right-click your file in File Explorer and choose Add to Archive.
